Android仿微信发朋友圈浏览图片效果

这里面的图片是我上传到七牛的网络图片，加载图片是用ImageLoader,下面也有具体的ImageLoader配置。 
2.看一下适配器内容 
在说说列表适配器中去设置图片的适配器，图片的GridView是重写了一个不能滑动的GridView，重写一下OnMeasure();

public class MyAdapter extends BaseAdapter {

  private Context context;
  private List<ContentBean> data;

  public MyAdapter(Context context, List<ContentBean> data) {
    this.context = context;
    this.data = data;
  }

  @Override
  public int getCount() {
    return data.size();
  }

  @Override
  public Object getItem(int i) {
    return data.get(i);
  }

  @Override
  public long getItemId(int i) {
    return i;
  }

  @Override
  public View getView(int i, View view, ViewGroup viewGroup) {
    ViewHolder holder;
    if (view == null) {
      holder = new ViewHolder();
      view = View.inflate(context, R.layout.item, null);
      holder.gridView = (NoScrollGridView) view.findViewById(R.id.gridview);
      holder.tvName = (TextView) view.findViewById(R.id.tv_name);
      holder.tvTitle = (TextView) view.findViewById(R.id.tv_title);
      view.setTag(holder);
    } else {
      holder = (ViewHolder) view.getTag();
    }

    final ContentBean bean = data.get(i);

    holder.tvName.setText(bean.getName());
    holder.tvTitle.setText(bean.getTitle());

    if (data != null && data.size() > 0) {
      holder.gridView.setAdapter(new ImageGridAdapter(context, bean.getImgUrls()));
    }
    /**
     * 图片列表点击事件
     */
    holder.gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
      @Override
      public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        Intent intent = new Intent(context, ImagePagerActivity.class);
        intent.putExtra(ImagePagerActivity.EXTRA_IMAGE_URLS, (Serializable) bean.getImgUrls());
        intent.putExtra(ImagePagerActivity.EXTRA_IMAGE_INDEX, i);
        context.startActivity(intent);
      }
    });

    return view;
  }

  class ViewHolder {
    TextView tvName, tvTitle;
    NoScrollGridView gridView;
  }
}

3.然后就是图片浏览，这个网上也有好多的Demo，也有详细的讲解，直接拽过来用就可以了，下面的图片数量是监听setOnPageChangeListener（）来改变下面的图片索引值

/**
 * 图片查看器
 */
public class ImagePagerActivity extends FragmentActivity {
  private static final String STATE_POSITION = "STATE_POSITION";
  public static final String EXTRA_IMAGE_INDEX = "image_index"; 
  public static final String EXTRA_IMAGE_URLS = "image_urls";

  private HackyViewPager mPager;
  private int pagerPosition;
  private TextView indicator;

  @Override 
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.image_detail_pager);

    pagerPosition = getIntent().getIntExtra(EXTRA_IMAGE_INDEX, 0);
    ArrayList<String> urls = getIntent().getStringArrayListExtra(EXTRA_IMAGE_URLS);

    mPager = (HackyViewPager) findViewById(R.id.pager);
    ImagePagerAdapter mAdapter = new ImagePagerAdapter(getSupportFragmentManager(), urls);
    mPager.setAdapter(mAdapter);
    indicator = (TextView) findViewById(R.id.indicator);

    CharSequence text = getString(R.string.viewpager_indicator, 1, mPager.getAdapter().getCount());
    indicator.setText(text);
    // 更新下标
    mPager.setOnPageChangeListener(new OnPageChangeListener() {

      @Override
      public void onPageScrollStateChanged(int arg0) {
      }

      @Override
      public void onPageScrolled(int arg0, float arg1, int arg2) {
      }

      @Override
      public void onPageSelected(int arg0) {
        CharSequence text = getString(R.string.viewpager_indicator, arg0 + 1, mPager.getAdapter().getCount());
        indicator.setText(text);
      }

    });
    if (savedInstanceState != null) {
      pagerPosition = savedInstanceState.getInt(STATE_POSITION);
    }

    mPager.setCurrentItem(pagerPosition);
  }

  @Override
  public void onSaveInstanceState(Bundle outState) {
    outState.putInt(STATE_POSITION, mPager.getCurrentItem());
  }

  private class ImagePagerAdapter extends FragmentStatePagerAdapter {

    public ArrayList<String> fileList;

    public ImagePagerAdapter(FragmentManager fm, ArrayList<String> fileList) {
      super(fm);
      this.fileList = fileList;
    }

    @Override
    public int getCount() {
      return fileList == null ? 0 : fileList.size();
    }

    @Override
    public Fragment getItem(int position) {
      String url = fileList.get(position);
      return ImageDetailFragment.newInstance(url);
    }

  }
}
